Most Keto Chow flavors use the sweetener sucralose. (The exceptions are the savory flavors which contain no sweetener, Natural Strawberry which uses monk fruit, and the Core line which is either unsweetened or uses Stevia.) There is some confusion between Splenda” (that you buy at the grocery store) and pure sucralose. Splenda contains sucralose, but it also contains bulking agents so that you can “measure it like sugar.” Typically that means 99.8% maltodextrin—a carbohydrate that will spike your blood sugar and is not recommended for a ketogenic or low-carb diet. Pure sucralose, on the other hand, does not typically cause an insulin response. There is also very little of it in Keto Chow: about 0.08g per serving (about 1/64 the weight of a US nickel).
We use sucralose in the majority of our flavors because it seems to be what the majority of people prefer. Everyone has different preferences when it comes to sweeteners, of course, so we recommend trying our different options to find what works best for you.
What about the rat studies showing changes in gut bacteria when exposed to sucralose? Most importantly: humans are not rats. And also, the rats in those studies were consuming extremely high amounts of sucralose—several times more than what you would get even from consuming three Keto Chows daily. The researchers also failed to determine whether the results from the study were exclusive to sucralose, as they failed to test standard sugar, erythritol, xylitol, etc. This is one of the reasons why it’s important that you not rely on the “news” version that’s been enhanced with incendiary headlines but actually read the full text of the published papers.
